REFRIGERATOR.

SPECIFICATION forming part of Letters Patent No. 265,202, dated September 26, 1882.

` `Application filed July 3, 1882. (No model.) A

To all whom it may concern:

Be it known that I, CHARLES Gr. WIESNER, of Kansas City, in the county of' Jackson and State ot' Missouri, have invented a new and Improved Refrigerator, of which the following is a full, clear, and exact description.

The object oi my invention is to provide a new and improved refrigerator, of which the walls are so constructed that the non-conducting material cannot be destroyed by moisture, which refrigerator is also so constructed that considerably less ice will be required than in refrigerators ot' the usual construction.

The invention consists in arefrigeratorhaving its walls, top, and bottom made of three partitions, having paper or. analogous material placed between the outer and middle partitions, andhavin gan air-space formed between the middle and inner thicknesses.

The invention also consists in a smaller chamber arranged within the refrigerating-box and provided with a. swinging top and bottom, which are opened automatically when the door of the small compartment is closed, and are closed automaticallyl when this door is opened, whereby the warm air of the room is prevented from passing `into the large refrigerating-box, all as will be fully described and set forth hereinafter.

Reference is to be had to the accompanying drawings, forming part of this specification, in which similar letters of referenceindicate corresponding parts in all the figures.

Figure lis a longitudinal sectional elevation of my improved refrigerator. Fig. 2 is a crosssection elevation of the same on the line x w, Fig. 1. Fig. 3 is a plan view ot' theice-receiv- Y Fig. 4 is a detail side view of part of the refrigerating-box, showing the inner end of the levers pivoted to the sides.

The ice-box A hasits walls, top and bottom, each formed ot' three partitions of boards, a, b, and c, which are placed equidistant from each other, the space between the two 'layers c and b being filled with one or more layers of paper, d, or other analogous material, and an air-space being formed between the inner two layers b and c.

Refrigerators have been constructed heretofore with paper liningsand iillings in the walls; but as these nonconducting linings or fillings were subjected to the moisture they soon rotted and became useless. In my improved refrigerator the moisture cannot act on the non-conduct The ice-receiving box B rests on a series of 6o slats, D, held in a frame, E, in the upper part ot' the rei'rigerating-box A. Below these slats D a series of grooved slats, F, are held,which rest on and are attached to a cross-frame, G, resting on a cross-shaft, H, which passes through the curved slots H in the sides of the refrigerating-box A, and is atta-chedto the inner ends of the levers J, pivoted to the outer surfaces ot' the sides of the refrigeratingbox A, and can be locked in the desired position by means ot' racks K, attached tothe refrigerating-box. Blocks'H2 are attached-to the outer ends of the shaft H on the outer surface of the sides of the box and in the air-space between thc walls b and c, and slide up and down with the shaft, which blocks are of such size that they always close the slots H', and are covered with rubber or other packing to prevent the entrance of hot or Warm air into the refrigerating-box A. The drip-water from the ice-receiving box liows down the grooved s lats F to one end ot' the box A. These slats Fcan be adjusted at anyY desired inclination by means of the vlevers J and the racks-K, for by pressing down the outer endsof these levers J the middle of the frame Gr, supporting the slats F, will be. raised and theslats Will be placed in a more horizontal position.

A small chamber, L, is formed in the large refrigerating-chamberA, and is used forlsmaller articles. door, M, containing a glass pane, M', through which the articles contained in the chamber or box L can he seen. Forinstance,large pieces of meat-such as quarters of beef and the likewould be stored in the large icebox, while smaller pieces, dressed meats, 85e., would be stored in the small compartment L. The small compartment is especially adapted for such articles as are required frequently. The top N and the bottom O of the small compartment L are hinged so as to swing upward and downward, respectively. Elbowdevers P are This chamber is provided witha IOO hinged to the swinging top N and bottom C e v sesgos at the under and upper surfaces, respectively,

and thev opposite ends of these elbow-levers P are pivoted to rods Q, passing through the inner side wall of the'chamber or box L.

The door M is provided at its outer or swing ing edge with two tongues, R R, which strike against the projecting ends ot' the rods Q, Q, when the door M is closed.

The chamber is provided with a door, S, of the usual construction, providedwith a glass pane, T.

A thermometer is placed in the compartment L, and can be seen through the glass pane M of the door M.

The top N and bottom O of the compartment L are generally held closed 'by their own Weight when the doorM is open, the ends of the rods Q projecting from the box A at the side ot' the door. No cold. air can then pass from the chamber A into the compartiment or chamber L, as all communication is then cut olf. It' the door M is closed, the tongues R push the rods Q inward, thereby pushing the top N upward and the bottom O downwardthat is, opening the top and bottom, and thus permitting the cold air to circulate through the compartment L, and thus refrigerating the articles in -the same. As soon as the door M is opened the tongues R release the rods Q, thus permitting the top N and bottom O of thel chamber Lto close. rDhereby agreat waste vented.

The refrigerator has an aperture, W', in thc bottom, through which aperture the foul air in the refrigerator-walls can pass oft'. Double glass windows are used, so that air-spaces will be formed between the glass, and the panes will not sweat.

The ice-chamber is preferably constructed so as to leave an air-space on the sides through which the air can pass upward.

Having thus described my invention,-I claim as new and desire to secure by Letters Patent- 1. In a refrigerator, the grooved slats F, arranged beneath the ice-box slats D, in combination with a vertically-movable frame, G, a cross-shaft, H, having end blocks, H2, and the box A, having curved slots in the sides, as and for the purpose specified.

2. The box L in chamber A, having a hinged top and bottom, in combination with the rods Q, the elbow-levers P, pivoted to said rods, the door M, having tongues R, and the glass-patted door S, whereby said chamber may be used, as described.
